Stainless steel flanged check valves 16nzh10nzh made PN 16 are lifting check valves that are used to prevent backflow of the working medium in pipelines. The main purpose of the valves is to protect the system from damage caused by the reverse movement of the medium, which can occur with sudden pressure drops.
Operating principle
Installation and operation
Valves 16nzh10nzh are installed on horizontal pipelines with the cover facing up. When installing the valves, it is necessary to ensure that the flanges are installed without distortions and coincide with the holes in the pipeline. The valves should be installed on sections of the pipeline accessible for inspection and maintenance.
